Finally took a picture of my chaos super heavies. From the left we have my Tzeentch Warlord. In front of that we have my Slaanesh Warhound. Next is a Slaaneshi Reaver then a Khorne Reaver. My Silver Tower is after that, followed at the far right by the Slaanesh "Pleasurelord" Warlord.
I was a little worried how the two Warlords would work together, but neither outclasses the other. They do make the Reavers look pretty small, though.
Let me know what you think!
